  • Cezana Jr., Miguel; Tenenblat, Keti (manuscripta mathematica, 2017-09)
    We consider proper Dupin hypersurfaces of the Euclidean space ℝn+1, that admit principal coordinate systems and have n distinct nonvanishing principal curvatures. We obtain explicitly all such hypersurfaces that have ...
  • Cezana, Miguel Jr.; Tenenblat, Keti (Monatshefte für Mathematik, 2014-10)
    We consider Mn,n≥3, umbilic-free hypersurfaces in the Euclidean space, with nonvanishing principal curvatures. We prove that M is a Laguerre isoparametric hypersurface if, and only if, it is a cyclide of Dupin or a Dupin ...
  • Borges, P. D.; Petersen, J. E.; Scolfaro, L.; Leite Alves, H. W.; Myers, T. H. (Journal of Solid State Chemistry, 2015-07)
    Doping in a manner that introduces anisotropy in order to reduce thermal conductivity is a significant focus in thermoelectric research today. By solving the semiclassical Boltzmann transport equations in the constant ...
  • Pinho, Gevany Paulino de; Neves, Antônio Augusto; Queiroz, Maria Eliana Lopes Ribeiro de; Silvério, Flaviano Oliveira (Food Chemistry, 2010-07-01)
    In this work, a simple and low cost method, based on solid–liquid extraction with low temperature purification (SLE–LTP), was optimized and validated for the determination of chlorpyrifos, λ-cyhalothrin, cypermethrin and ...
